Why does it say “rule already exists “ when manually categorizing a trip for mileage? Surely if the rule existed I wouldn’t have to manually categorize it.

Let's work through troubleshooting your QuickBooks Self-Employed (QBSE) mobile app to ensure you can manually categorize your trips for accurate mileage tracking, Victor.

Accumulated data on your device may affect its functionality. To reset it while keeping your app's documents and data, please follow these steps:

For iOS:

1. Go to Settings, then tap General.
2. Select iPhone Storage, then click the QuickBooks Online app.
3. Tap Offload App.

For Android:

1. Go to Menu ☰, then tap More Options ⋮.
2. Navigate to Settings, then Refresh Data.
3. Click YES to confirm.

If the issue persists, I suggest uninstalling and re-installing the app to ensure it is up to date.
